Students at Beijing's Yucai High School have to be very careful when playing football on the school's field. That's because there is a 100-year-old tree growing in the middle of it. And keeping their eye on the ball too much can result in a painful collision(撞击).
     Building a football field around a tree sounds pretty stupid. But the school had no choice. It's reported that there are historic(有历史意义的)buildings all around Yucai High School,and this was the only space that could be used for a football field. Before starting working on the field,the school did ask to have the tree moved and planted somewhere else. However,they were told that it was hundreds of years old, and that it was a national treasure. Having it moved and planted somewhere else was too risky(有风险的) - they might damage or kill the tree. So they were left with no choice but to build the field around it.
     Interestingly,Yucai High School is built on the grounds of Beijing's Royal Gardens of the Ming and Qing dynasties(朝代). A reporter for the Beijing News believes that the strangely-located tree is the oldest tree in the Chinese capital. That information has not been checked,but other people think the tree is only 100 years old.
     Playing a serious game of football on this field cannot be very pleasant. The tree could "catch" the ball and change its direction from time to time. But the students have no choice but to train on the playground with the tree. Luckily, they can play on a different field in competitions with other schools.
